           The unit of analysis is the directed country dyad year. 
             Baseline controls: relative territorial size of state A vs. state B; logged absolute size of country B; 
             indicators for whether governing group in A has governing or powerless kin segment in B;   
             dummies for peace and calendar years.  
             Extended controls: logged aggregate group size of governing segments in A and B;
             ethnic fractionalization of countries A and B;
             Share of aggregate group governing in state A located in state B;
             Share of aggregate group governing in state A located in own country;
